Am trying to setup logic level converter with arduino for eps8266 WiFi module. Am using this logic level converter but it’s not working not sure what am doing am not getting any output.
My circuit
Red wire : 3.3v power source
Orange wire : 5v power source
Blue wire : ground.
Yellow wire : arduino TX1 on B2
White wire : output on A2
Multi meter it red wire : 3.3 v showing on display
Multi meter it orange wire : 4.68 v showing on display
Multi meter it yellow wire : 4.36 v showing on display
**Multi meter it white wire : no voltage showing on display ??? **
Update : have set OE pin to enable and swapped red and orange. Still no output for yellow wire
